Introducing the Nina Spl-Claim Program

A Proof of Concept for a Tokenized Access-Control Mechanism

Are you still using spreadsheets, Google Forms, DMs, passwords, and access codes to grant early/closed testing access to users?

Why?

A blockchain is a distributed ledger - it is no longer necessary to rely on legacy accounting practices to keep track of who has a right of access or who made a claim before someone else.

This can all be represented by simply holding a completely arbitrary token. A token that has no value or purpose other than representing a spot in line - a key to a protected area. Since Solana is so fast and cheap there is basically 0 overhead to using tokens this way.

The Nina Spl-Claim Program streamlines the process for a developer to mint an arbitrary amount of tokens, at arbitrary times, that can provide access to a closed beta test.

A developer using the program creates a faucet, fills it when they want to provide more access, burns it when the want to close access. Their users can then claim a token (one per wallet) - which grants them access to the closed beta test. This takes the accounting burden off the developers, while the users can rest assured that access was given out in a first-come-first-served manner. Perhaps users will create secondary markets for these Claim-Token invites. Perhaps people will use this to keep account of who is eligible for airdrops (paired with the Solana Name Service to ensure claims cannot be made by bots) - you can't really tell what people will do with a new technology.

Anchor

Setup Anchor following the instructions in the 'Getting Started' docs.

To run tests: anchor test

To deploy the program yourself: anchor deploy

RPC Client calls

To create a faucet:

node client/initialize.js

[Take note of the Faucet Program Address printed out on initialization. You will need to set FAUCET_ACCOUNT in /app/src/utils/faucet.js and /client/faucet.jsto this value as well .]

To fill the faucet:

node client/refillFaucet.js

To burn unclaimed supply and close faucet from new claims:

node client/closeFaucet.js

Frontend Example

A basic ReactJS frontend is provided in /app - in this example only holders of the Claim-Token for this app have access to /app/src/components/ProtectedArea.js

To Run:

1. cd app
2. yarn
3. yarn start
